MECHANISM FOR DRIVING SPlNNlNG-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 465,001, dated December15, 1891. Application filed August 5, 1891- Serial No. 401,741. (Nomodel.)

To all whom it may concern:

Be it known that I, CONRAD SCHREPFER, of the city of Paterson, in-thecounty of Passaic and State of New Jersey, have invented a new anduseful Improvement in Spindles for Spinning and Mechanism for Drivingthe Same, of which the following is a specifica tion.

My invention consists in an improvement in mechanism for drivingspinning-spindles, whereby an accelerated velocity at a regular uniformrate may be obtained Without the use of driving cords or belts, as isthe case with those in present use. With this arrangement of driving itis obvious that a greater amount of product is obtained of a .muchsuperior degree of quality with regard to the equal and regular twistgiven to the strands than is usually obtained; also, I attain by myimprovement a longer life for the spindle and its bolster and lessen theamount of power requisite to impart motion and to continue the same athigh velocities by reason of the amount of contact-pressure given "tothe friction-pulley of the spindle by a facewheel operated by springsattached to a driving-spider keyed to a driving-shaft located on eachside of the frame; also, I gain an equality of motion to the spindles oneach side of the frame by the gear-wheels and endless chains with theirsprocket-wheels located on the end of the frame or system of spindles.

Another advantage I obtain is the facility with which a single spindlecan be removed and replaced when so desired without stopping the frameor any of the other spindles, it being necessary only to force the facedriving-wheel back on the springs and closer to the spider, which willpermit the spindle to be withdrawn with ease, the springs pressingagainst the face-wheel with sufficient force to cause the same to drivethe spindles and not forcibly enough to throw a violent pressure againstthe bolster.

Another advantage I obtain by my invention is dispensing with thelongitudinal rails and substituting in their place transverse saddles,which are formed to receivea spindle at each extremity, and which may beeasily removed and replaced by loosening a single bolt. With the rail inuse at present, in the event of an accident, the whole frame has to bestopped to repair it when broken. I obtain these advantages bymeans ofthe mechanism illustrated in the accompanying drawings, in which- Figure1 is a part front elevation of a single spindle in engagement. Fig. 2 isa side elevation of the same, part sectional. Fig. 3 is a part elevationof one arm of the face driving-wheel, showing hole in arm to receive thepin guiding or holding in position the tension-spring. Fig. 4 is asectional View of part of the spindle-bolster and the drivingmechanism,showing the face driving-wheel forced back to allow thewithdrawal of the spindle. Fig. 5 is an elevation of. the end of aframe, showing the mechanism for communicating motion to each side andthe winding-bobbins. Fig. 6 is a part front elevation of a frame,showing the driving-shafts and spindles in their relative positions.

I will now proceed to describe the construction of my invention relatingto spinningspindles. Arranged on and attached to an end stand or framea, one of which is located at each end of the machine, (and in case ofma-' chines of great length or number of spindles others are placedintermediate,) is a longitudinal bar F, on the upper edge of which aresecured by suitable bolts E the transverse saddles E,with their holdersD formed to receive the bolsters O of the spindles A, and which aresecured by the set-bolts D. The saddles are located on the bar F at sucha distance apart as to allow a sufficient space between thedriving-spider L of one spindle and the bolster of another to permitfreedom of access, as shown in Fig. 6. On each side of the frame a and journaled in bearings formed to receive them are the longitudinaldrivingshafts K, to which and upon which are arranged thedriving-spiders L, secured by the set-screws N firmly to the shaft K.The hub of the spider is formed at one end with two projecting lugs N toengage similar projections or lugs M on the hub of the facedriving-wheel P. On the three arms of the driving-wheel I guide-pins Rare located, projecting outward a sufficient distance to enter looselyinto the elongated holes P, formedin the arms of the face or plate wheelP to receive them, as shown in Fig. 3. On the guidepins Rare arrangedspiral springs S, one end freely on in Figs. 5 and 6.

in pressing contact against the back of the face driving-wheel P and theother against the arm of the spider L, as shown in Figs. 1, 4, and 6.The face driving-wheel P has an angular face P turned true and smooth,which face is forced against the friction-pulleyB of. the spindle A bythe springs S, the wheel P being bored somewhat larger, so that thediameter of the shaft K slides freely into engagement. Thefriction-pulley B is preferably made of hard rubber and isturnedrounding on the edge, as shown in Figs. 1 and 4. The spindle A is of theusual form and held in position by the bolster O, which is secured inthe bracket E, as before described. On the extreme end of one ofiheshafts K is affixed a driving-pulley a, secured by any suitablemeans, and on both the shafts K K close to the end of frame a arethesprocket-wheels aiwhich are both of the same diameter and fastened inany suitable manner. The peripheries of the wheels a are provided withprojections to interlock with indentations in a flexible metallicendless chain f, formed with suitablelinks, which connects the twowheels a as shown On the shaft K is secured a sprocket-wheel d, ofsmaller diameter than the sprocket-wheels a with similar projections toengage the links of a flexible endless chain f. Located on a stud d,secured to? the side of the end frame a, and fastened by the pin (1 is alarger sprocket-wheel d, with -projections on the periphery to engagethe endless chain f, as before described. Attached to and forming partof the wheel (I is a toothed pinion h, which, with the wheel d, revolvesthe stud d On'the stud k similarly located on the side of the end framea, is an intermediate pinion h, which gears into the pinion h andthegear-wheels e and communicates motion to them. The gear-wheels e arekeyed on the ends of shafts e, arranged longitudinally in suitablebearings on each side of the upper part of the frame a, as shown inFigs. 5 and 6. Arranged at a suitable distance apart on the shaftse arelocated friction-pulleys e in line vertically with the spinbins are helddies A, which engage the winding bobbins when placed in the frame. Ontop of frame a and extending its whole length and secured by suitablebelts or, screws is a table b to hold bobbins, and to the under side ofwhich are hung the cradles in whichthe winding-bobwhen the machine orframe is in operation, as shown in Figs. 5 and 6.

I will now proceed to describe the operation of myinvention. Motionbeing given by belt in the usual manner'to the pulley aflit rotates theshaft K and by means of the sprocketwheels a and the endless chain f theshaft K. The spiders L, being secured to the shafts K K by the set-screwN by means of the lug N being in juxtaposition with the lugs M of theface driving-wheels P, imparta. similar rotary motion to the wheelsP,the,faces P of which being turned at a suitable angle are forced intocontact with the whirls B of the spindles A by means of the springsS,located on the pins R, which form part of the spider L and impartaccelerated motion to the spindle A. When any spindle or its pivotalbolster 0 requires removing, a slight pressure applied laterally to thewheel P will compress the springs S sufficiently to allow the wheel P toslide back and out of engagement with the friction pulley l3, freely onthe shaft K or K. Sufficient frictional tension is given to the springsS to act against the wheel P and spider Lby closing in the spider Lnearer to the Wheel P, compressing the springs S, and when adjustedsecuring the set-screw N. Aspacesnfficient to allow for the action ofthe-springs, S. is left between the ends of the lugsMand Non theplatewheel P and spider L, as shown in Fig. 1. On the shaft K in frontof thesprocket-wheel a is seen red by a suitable key a smallersprocketwheel (Z which, being put in motion by the shaft K by means ofthe endless chain F, communicates a rotarymotion to the largesprocket-Wheel d and the pinion h, which revolve on the stud d and whichare held in position by the pin 01 as shown in- Fig. 6. The pinion himparts in its turn-motion to the idle-wheel h, which is located on thestud h and upon which it turns freely. The idlewheel h imparts oneachside ofgits. periphery motion to the gear-wheels which are securedto the end of the shafts e, which extend longitudinally the length ofthe'frame on each side, as shown .invFigs. 5,-and 6. Located on theshaft cat suitable distances and secured with set-screws are the pulleyse, which, being put into revolution by their shafts e, impartmotion tobobbins or other mechanism when brought intocontact with their faces inthe course of themanipulation of the material being manufactured. Thediameters of the geanwheels e pinion h, sprocket-wheels d and (1 andwheels a -aresuchas will secure a sufficient tension andwill remove thematerial being operated upon as fast as the revolving spindle S willdeliver it.
